T 0 all whom t may concern Be it known that LHARM FRANZEN, a citizenof'the 4United States, residing at Phoeg nix, inthe county of Maricopa and State of Arizona,'h ave invented certain new and use ful Improvements in Runners for Sickle? Bars, of Awhich the following isa specification. A

i This invention relates to attachments for mowing machines and the like, which embodies afswinging cutter bar,vand is animprovement on my patented application issued to me Feb. lst 1921, Patent No. 1,367,- 367 and the primary object of the present invention is to provide an improved runner for-mowing machines adapted to be carried by the cutter bar thereofintermediate the usual supporting shoes, which can besecured to any size cutter bar, thereby permitting the runnerto be used with all types and makes of mowing machines. f

A further object of he invention is provide an improved runner for supporting Ethe cutter bars of mowingmachines em-V bodying `a rearwardly extending arcuate; resilient plate, and an attaching foot for engaging one face of the cutter bar, and an' adjustable finger for engaging the opposite face of the cutter' bar, the adjustable linger forming va novel and convenient'means for attaching the runner to all widths andthickness of-v cutter bars. f

'With these and oth'erobjects in view, the

invention consists in the novel construction,

arrangement and formation of parts, as will be hereinafter more specifically described,

claimed and illustrated in the accompanying' drawings, forming. apart of this specifica- 'ftion, in which drawings:

.Figure l is a perspective viewof -a mowing -machine provided with the improved runners.

B, which has associated therewith the ini-f proved runners C. *Thefcutter bar B of thev mowing machine A is provided with the usual outwardly lextending guardlfingers 5,

When a pair of therunners C are utilized,

one ofthe same is arranged adjacent to the outer end of the cutter'bar andthe other is arranged adjacent to lthe inner end ofthe cutter bar. y"These runnersv C are'adapted to* project rearwardly and downwardly from the' cutter bar Band rare adaptedto support the cutter bar, when the usual shoes 7`ride into avditcho'r-other` irregularity formed in the surface of the ground over which the mowing machine is operated, Aso asjto carry the cutter. bar -abovegthe ditch and i thus prevent* the if teeth T5 4from digging fintov the ground. Each of the runners C includes: a relatively narrow elongated body 8, formed of anylmaterial, but preferably ofresilientl steel. f The 'elongated bodyv 8 Aincludesthe downwardly and rearwardly arcuately extending portion 9, which las'its outer end vbent upwardly slightly, as indicated by the numeral V10. If so desired, the bodyk 7 `may begradually decreased inthickness toward its`outer or free end soasto enhance the resiliency thereof.

AThe inner end of the elongated body'LSy is provided lwith a forwardly'eirtending 'substantially horizontally disposed attaching foot ll, whichas-shown in the drawings, is

. adapted to be" placed in abutting relation to vthe upper face ofthe cuttervbariB, directly abov'efone of theguard teeth 5. The attaching -footllis adapted'tol be secured' to the cutter bar B Vby means of'a removable bolt,

fico

and as shown infFig's. 2 and .3 ofthejdrawings, the same bolts utilized for connecting 5 the' teeth 5 Yto the cutter bar B may be utilized -for holding the runner in place. It is to b e'understood, however that otherbolts may be employed ifso desired. A clamping meinberlQ is adapted to engagel the face of the cutter bar opposite to the face engaged by the attaching portion 11, and forms an additional support for the runner so as to prevent undue strain on the attaching-.bolt

y of the attaching foot.

If desirable the foot 11 may be placed in yengagement with the lower face of the cutter bar andthe clamping member placed in Y engagement with, the upper face off the cutter bar. Thsis directlyopposite to what is shown in Figs. 2.and 3, and it can be seen that the cutter bar will be positioned a little higher from the-ground, when the foot 1.1

Y is placed in engagement with the lower face.

of the .cutter bar than when it is placed in engagement with the upper face of the cutter bar. v Y Y This clamping member 12 is adjustablyl mounted upon the runner, soas'to permit the runnertobe connected to -all widths and thicknesses of cutter bars, so thatV the device can be connected to all makes-of mowing machines.A As shown, this clamping member 12 includes the right angularly disposed attaching portion 13 for engaging the runner, the forwardly and downwardly extending body portion 14 and-the cutter bar- If so desired thev cutter bar engaging portion 15 maybe proengagingV portion 15.

vided witha sharpenedbiting tooth 16 for ffirmly engaging the lower surface of the cutter bar. The runner engaging portion 13 is provided with an opening 17 for the ;recep l tion of an attaching bolt 18, which is arrange, in ,a longitudinally extending slot 2() formed in the runnerjC. A suitable locking the runner tobe attached at any position nut 21 is threaded uponthe attaching bolt 18,

toward and away from the runner, so as to accommodate various thicknesses of cutter bars. Y Y

Y Thus, the improved runner can be attached toall makes of mowing machines. In some types of mowing machines, the cutterA bar is gradually tapered toward Vits outer end, and the arrangement of the runner C and the clamping member `12, permits along the cutter bar.

' In use the improved runner, the same being positioned intermediate the shoes 7 and in'rear thereof, effectively supports the cutter bar when the ordinary shoe rides into a ditch, thereby preventing .theguard fingers from digging into the groundand becoming broken. The runners are also particularly adapted for use on fields on which the ground is broken or irregular, and as clearly shown in Fig. 3, when the ordinary shoe or guard `rides into adepressed portionof the ground,

the improved runner() will support the cut- V'terbar until the shoe rides out of thesame.

`Changes, in details may be made without departing from the spirit or scope of the invention; but,

Iclaim:

t l. In a mowing machine, the combination of acutter bar, of a runner attachment therefor including an attaching foot for engaging one face ofthe cutter bar, a fastening element arranged to extend through the said foot and cutter bar, said runner having`l a slot therein, a clamp for engaging the face of the cutter bar opposite to theV faceY en? gaged by the attaching foot, and an adjusting bolt carried bythe clamp and slidably mounted in said slot.-

2. In a mowing machine, the combination with a cutter bar having a plurality of teeth', of a runner attachment thereforv including an arcuate rearwardly extending and de-j pending body, and an attaching foot for en- 1 gagingV the upper face of the cutter bar,jav bolt extended through the foot, thecutter bar, and one vof the said teeth, 1a forwardly extending clamping member arranged'to en gage the lower face'and rear 'edge ofthe cutter bar, and anv adjusting bolt carried by the clamping'member and therunner in rear of lsaid attaching foot.

3. A runner comprising a latielongated narrow body including a downwardly and rearwardly curved portion, and a forwardly extending attaching foot,thel body having a longitudinally extending slot formed therein adjacent to the attaching foot, a' clampingl member including a. forwardlyrand downwardly extendingportion, and a rearwardly extending body engaging portion, thel body engaging portion having an opening therein, a bolt extended through said opening and slot, and a nut threaded onfsaid bolt. v

4. A runner comprisingfa fiat elongated narrow body including a downwardly and rearwardly curved portion and a forwardly extending` attaching foot, the bodyhaving a longitudinally extending slot formed therein adjacentto the attaching foot, a, clamping member. including a Vforwardly and downwardly extending portion and a rearwardly Yiio extending body engaging portion, the body engaging portion havingan op'eningrtherein, a bolt extended throughV said vopeningand slot, a nut threaded on'fsaidbolt, and a bit-` ing tooth 'formed on theforward end of said' e clamping member.
